DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an electric hair clipper, and relates to a head case pivotably connected to a grip case.

The blade unit, which has a movable blade and a fixed blade, is designed to be removably attached.

[Background technology]

Regarding this kind of electric hair clipper with a swinging head type.

Although it has already been proposed by the applicant, in this case, as shown in FIG.
a, the fixed blade 63 and the movable blade 6 that slides on the upper surface of the fixed blade 63.
The grip part case 1a and the head case 1b are divided into two positions: a basic position where the head case 1b is substantially straight with the grip part case 1a, and a position where the head case 1b is tilted upward. It is pivotally connected around the support shaft 3 so as to be freely swingable.

In this way, when the head case 1b having the fixed blade 63 and the movable blade 64 is configured to be swingable relative to the grip case la, the head on the blade edge side of the main body case such as a general electric hair clipper and the grip The parts are completely integrated in a straight line, and the fixed blade is carved into the head of the main body case so that it remains at a constant angle.

Compared to equipment that is equipped with a single blade, it is possible to have more versatility in cutting methods, and it is possible to use a mode suitable for each cutting method. Namely.

Under the basic posture in which the head case Ib is in a straight line with the grip part case 1a, it is easy to use when shaving, lanugo hair cutting, etc.

The head case Ib faces upward 191 with respect to the grip case la.
If you turn it upside down and use it in a diagonal position, you can cut it evenly around the ears or at the edges.

It can be suitably used for shaving, cutting bangs, etc.

However, in such an electric hair clipper, it is necessary to make it easy to maintain the fixed blade 63 and the movable blade 64 and to remove hair debris. Therefore, the fixed blade 63 and the movable blade 64 are made into a unit, and this blade unit 33 is detachably attached to the head case 1b.

The problem is the detachable mounting means for this blade unit 33.

For example, as shown in FIG. 1, in this type of electric hair clipper with a swinging head, the blade unit 33 is hinged 80 on the rear αI"1) side opposite to the blade edge with respect to the head case 1b.
The front end of the head case 1b is pivotally connected to the head case 1b so as to be swingable back and forth, and the front end side of the head case 1b is detachably held through a locking means 8I. In such a case, when removing the blade unit 1-33 from the first head case 1b, put your finger on the blade edge of the blade unit throat 33 that protrudes forward of the first head case 1b and forcefully push the blade unit 33 downward to remove the locking means. 81 is disengaged, and the blade unit 33 is swung downward and backward around the hinge 80, and the engagement point at the hinge 80 is separated by A11-i-. When removing the blade unit 33 in this way, When this is pushed strongly downward, the front end of the head case 1b is also pushed strongly downward, causing the swing shaft of the head case 1b and the lead swing square;
If an excessive load is placed on the l and tJ parts or the parts are strained, the swing shaft part and the swing angle regulating part are likely to come off or be damaged. Also.

Hair and oil adhering to the blade tip cause discomfort on the fingertips.

It hurts when your fingers touch the edge of the blade, and women and girls in particular feel scared and have difficulty handling it.

[Purpose and outline of the invention]

The present invention was made to solve this problem in a single swing type electric hair clipper.

By making the blade unit slidable in the front-rear direction orthogonal to the swinging direction of the head case through a locking slide means consisting of a sliding protrusion and a guide-groove in which this slide fits and slides, the head can be attached and detached. The first object is to enable a blade unit to be removed without applying excessive negative force to the swing shaft part or swing angle regulating part of the case, and without touching the blade edge with a finger. Further, the engagement slide means for the head case of the blade unit is positioned approximately on the same line as the front-rear direction line passing through the center of the swinging support shaft of the blade unit.
The second object is to ensure that the head case does not swing four times unexpectedly when the sword unit is installed, thereby facilitating the installation process. Hereinafter, five embodiments of the present invention will be described based on the drawings.
